The object of research is means and algorithms for controlling voltage, current and frequency in hybrid power systems of electrotechnological installations with incomplete determination of load parameters.
During the reporting period, scientific research work was carried out in accordance with the corresponding stage of the work plan for 2023. In particular, new tools and algorithms for regulating voltage, current and frequency in electric drives and electrotechnological installations using hybrid power systems and intelligent control systems have been developed, which fulfill technical requirements in the case of incomplete determination of load parameters, provide specified indicators of the quality of current consumed from the network and electromagnetic compatibility with power network. Basic practical schemes of means of voltage, current and frequency regulation, which have the greatest prospects for their implementation, have been developed and corresponding mock-ups have been made. A new approach to the construction of electric drive systems of radar station antennas with gearless arc stator electric motors is proposed based on the use of a relatively simple and reliable, from the point of view of technical implementation, fuzzy proportional-integral-differential speed regulator. The synthesis of the fuzzy regulator of the speed of rotation of the antenna of the radar station was carried out. Planning on a fuzzy logical conclusion is based on the Mamdani algorithm, which is formed according to a base of rules compiled on the basis of expert experience. Control of the electric drive of the station antenna is formed by a fuzzy controller based on the signals of the digital speed meter and antenna rotation angle (encoder) and the wind speed meter (anemometer). The results of the synthesis of the fuzzy regulator are confirmed by simulations in the Matlab environment. The results of simulation of the most difficult mode of operation of the antenna presented in th
